Improvement in steam-heaters



UNITED STATES PATENT FFICE.

CHARLES WHITTIER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HIMSELF ANDBENJAMIN F. CAMPBELL, OF SAME PLACE.

IMPROVEMENT IN STEAM-HEATERS.

Specification forming part of Letters Patent No. 86,1180, dated February2,1869.; antedated November 10, 1868- To all whom it 'may concern:

Be it known that I, CHARLES WHITTIER, of the city of Boston, in theState of Massachusetts, have invented certain new and usefulImprovements in Steam-Radiators and do h ereb y declare the following tobe a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the iigures and letters markedthereon.

Of these drawings, Figure 1 is a plan view of a number of sections of aradiator. Fig. 2 is' a longitudinal vertical section taken through theline a' x of Fig. 1,.and Fig. 3 is a cross vertical section takenthrough the line y y, or, in other words, a view of the cap, connectin gtwo sections, removed.

Similar letters of reference indicate corre` sponding parts in theseveral figures.

My invention relates to an improvement in radiators intended forindirect radiation, the sections being placed horizontally together orside by side, and one or more layers being properly connected andincased.

In :my application .for Letters Patent for improvements in radiators,filed contemporaneously with this, I find it difficult to cast perfectlythe sections therein mentioned more than four feet long. It is thereforenecessary,'when sections are required of a greater length, to cast thepipe separately, and then attach caps upon the ends of these sections,in pairs or alternately.

The round pipes have heretofore been attached to the caps by beingscrewed up to the latter. This was, however, found quite inconvenientand expensive.

For my class of radiator I cast a cap, e, as shown in Fig. 3, with fourlugs, b b b b, and also have corresponding lugs c c cc on the ends ofthe pipes d d, Svc., and these lugs contain slots e e e e at their outerends, into which are'inserted bolts ffff, each lug on the cap beingopposite to its corresponding one on the pipe. These bolts are providedwith nuts, so that they will, upon being tightened, draw closelytogether .the cap and pipes.

The cap is constructed internally so as to permit of the passage, fromone section of pipe to the other, of the thin body of steam in about thesame condition as it is while pass ing through such sections of pipe.

I do not mean to be understood as claiming 'i the round pipe connectedto caps with screws and nuts, as ordinarily practiced; but

What I do claim as new, and desire to se cure by Letters Patent, is

Sections of flattened pipes, the ends at tached, in pairs, by caps a,such caps being connected to the pipes by the lugs b b b-b, c o c c, andbolts f f f f, substantially in the mannerdescribed.
